T0 alii whom it may concern.'

Be it known that l, Len S.. tjnanrrrox, a citizen oi the United States, residing at Cleveland, in the county of Cuyahoga and State of Gino, have invented a certam new and useful: improvement in Burners, of which the `followirw' is a toll, clear, and exact description, re 'erence being had to the accompanying drawings.

This invention relates. to burners. for stoves and more particularly to Wick burners in the operation whereof the wiclr is, or may be, turned 'into engagement with ,an abutment (es part of tiro dame spreader) whereby its height is limited. lin the operation of burners ot' this kind and especiailv in the operation of the type shown in patent Ato learons No.- 848,828, wherein a drum surrounds the top of time Wick tubes and ertends tirereabove, it is customary to turn the wick up to its moet elevated position and to ignite the outer surface of the Wick through thedoor oi the drinn. No special harm will olow :troni this operation unless the door i o? tbe drnm'is left open. lin such case, `the prei-3er balance ci drafts withinthe burner anni within the drum is disturbed, the name licite around and greatly heats the spreader, increasing the Vaporination at the inner surface of the wick, and the vapor there produced falls by gravity downwardly within y 'time inner wick tube and becorn ignited.

@wing to tbe heating of the parte, the amount or ya or `time evolved becomes so great that .a eine or considerable volume may be produced, enicient to ons/cider the connections between the burner and the sup ply pipeand to alien the oil to escapo freely and be ignimd by this sme.

"lit is the objectfot this invention to provide moans whereby, inthe event or such fcme beingI produced Within the inner wick talee, en upward draft therefor may be anto,

'maticaliy' providedywhereby the parte liable to permit'tiie escape of oil Wi'li be protected .aga-inet' theI action of the Home end tire danger oi nre will. be eliminated.

Still' further and more generally speaking, the intention may be'deined further as consisting of the combinations or elements embodied the claims hereto annexed and iilnstratedin the drawings forming part hereof, niierein *iggnre i represents a vertical sectional rien through a burner and drinn tering my invention appliedthercto; Fig. 2 a sectional View correspondin tothe line 2 2 of Fig. l, lookzlng upward y; Fig. 3 a view similar to Fig l snowing the positions of the parts of tbe borner attertlee operation of my invention; and Fig. i is a ,sectional etai] illfnetrnting a modifcation of the invention shown in tiro preceding gures.

Describing by reference characters the vaincus parts illustrated lier-ein, l represente the inner and 2 the outer wick tube of,

the burner. 3 denotes the Wick Within said tubes, said Wick being provided with a carrier 4r which is adapted to loe engaged by the usual star Wheel on the Wiclrraiser shaft 5.

6 denotes a laterally projecting coupling which is soldered to the lower outer surface of the outer Wick tube and which is provided with a channel 7 Whereby'communication is established between the burner supply pipe (not shown) and the space between the Wick tubes, The connection 6 lmay loe secured in operative relation to the supply pipe in any desired manner, as for instance in the manner shown in -the patent to Jeavons No. 1,039,950, issued @ctober l, i912.

8 denotes the outerand 9 the inner ring of a centering* device for the spreader, said rings being connected by the inclined arms 10.v The inner rino forms a guide for the spindle ii, which is connected to the flame spreader. Irlilnis spreader is of the type shown in the deavons Patent No. 951,612, issued March 8, 19t() and, when in place, the

lower plate l2 thereof is in engagement with the top of a cylindrical ring i3 which eX- tends upwardly from the perforated frusto conical vring le, the lower cylindrical end angzge L whereof is secured to the upwardly projecting ring i6 which, together with the attached cylindrieai end dange 15 is supported upon the outer ring 8 or the centering device. The rin in entends somewhat above the tops of t e Wiclr tubes, and its upper end is detiected inwardly, ae shown atti', rilie rings ift and lo wiil be provided with pertorationn'and, if round desirable some of the perforation@ or the ring 16 may be located in the projection i7 thereof. The parte 13, le and l5 constitute an internal air distributor.

l denotesI a perforated plate which ex'- tends transverseiy across the bottom of the truste conical portion le of the air disair distributer.

tributer. This plate is rigid with the other parts of the distributer and carries at its lowei` end a locking device 19 which is adapted to engage the arms 10 in the manner shown, described, and claimed in Jeavons Patent No. 871,593, issued November 15, 1907.

It will be noted that the spindle 11 passes through the central portion of the plate 18 and through the ring 9, the spreader 11a carried thereby being centered by said ring and plate. When in operative position, the lower spreader plate 12 is in contact with the top of the cylindrical extension 13 of the A spiral spring 20 surrounds the spindle 11 and bears at one end against the top, of the plate 18, which constitutes an abutment for this end of the spring, and at its other end against the spreader, which constitutes an abutment for such other end of the spring, whereby the spring tends to elevate the spreader and the spindle and to separate the bottom of the spreader from the top of the distributer. To retain the spreader in operative relation to the wick tubes and the air distributor, a washer 2l is applied to the spindle beneath the plate 18 and is soldered to said spindle, the soldering surface being` extended by the neck 21a. A solder fusible at a comparatively lou7 temperature will be employed.

From the foregoing description, it is believed that the operation will be readily understood. iissumingB that the operator leaves the door 22 o3? the drum 21 open, with the wick 3 in substantial engagement With the lower spreader plate, and that'the flame unduly heats the spreader that the vapors evolved from the inner side of the wich are ignited within the Wick tube. Before any injurious results can be produced, the solder by which the Washer 21 is attached to the spindle 11 `will have been melted, and thereupon the spring 20 will elevate the spreader and the spindle, frequently,

with sucient Aforce to cause them to assume the position shown in Fig. 3. tree and unobstructed for the vapors Within the interior of the inner wick tube is then provided, and the wick will operate in substantially the same manner as an ordinary burner of the wick type and Without any serious danger to the operator, the burner parts, or the apartment Within which the stove or burner vmay be located@ ln Fig. i there is shown a modieation ofthe means for holding the spreader and the spindle in operative relation to the Wick tubes and air distributer. ln this gure, a washer 22 is applied to the spindle 23, above a fusible pin 24, which extends through a suitable hole in-.the spindle. The operation,

however, is substantially identical with that ot the preceding modification, the. heat produced by the ila-me in the inner- Wick tube ideama being sufiicient to melt the fusible pin 24 and to permit the spreader to elevate the spindle.

Having thus described my invention, what` I claim is 1. In a burner, the combination of inner and outer Wick tubes, a spreader extending above the upper ends of said tubes and spaced therefrom, a Wick Within the space between the Wick tubes, and means operative by temperature changes for automatically 'moving the spreader away from the top of the Wick tubes.

against the, action of the spring. j
